The present invention relates to a brazing automation device, and more specifically, to reduce the temperature deviation of the two or more base materials of different thicknesses, to maximize the bonding strength by brazing in the good wetting of the filler metal, the inflow of air The present invention relates to a brazing automation device capable of maximizing bonding strength by brazing a joined object in an optimal wetting state blocked and formed by a reducing gas atmosphere by an atmosphere gas.

As is well known, brazing is a joining of two base materials with a filler metal that is melted by a constant heat below the melting point of the base material, and this brazing heats below the solidus temperature of the base material. However, the two base materials are joined by a filler material having a liquidus temperature of 450 ° C. or more. In other words, the filler metal melted to reach a certain temperature, the capillary phenomenon, soaking between the two base materials to join the two base materials.

Here, the property of showing the affinity between the two base materials is called a wetting (Wetting), if the wetting of the base material to be brazed is poor bonding force is incomplete bonding is made.

Conventional continuous brazing automation device, a supply unit for supplying a base material having a filler material, a preheating unit for preheating the base material supplied from the supply base, a heating unit for heating to braze the base material preheated in the preheating chamber to the filler metal, A cooling unit for cooling the base material brazed in the heating chamber, a discharge table for discharging the cooled base material to the cooling chamber, a conveyor belt for continuously transferring the base material from the supply zone to the discharge zone, and driving the conveyor belt. It includes a drive motor connected.

The supply table is provided with a supply pipe, through which the flux is coated base material sequentially supplied to the preheating unit.

The preheating unit is provided with a preheating tube for transferring the base material, and the preheating tube has a built-in preheating heater to preheat the base material supplied from the supply table, and creates an atmosphere to form the preheated base material by the preheating heater in a reduced state. Atmospheric gas is supplied to the preheating tube. And the preheating unit is provided with a gas curtain to block the outside air flowing through the supply pipe supply.

The heating unit is composed of a plurality of chambers in which a heating heater is built in order to sequentially increase the heating temperature for heating the base material, and the base material gradually rises in temperature while being brazed into the filler metal while passing through the plurality of chambers. A plurality of chambers having different heating temperatures are provided with thermocouples, respectively, to measure internal temperatures. At this time, the atmosphere gas is supplied to the heating unit to create an atmosphere suitable for brazing.

Here, when looking at the heating unit more, when the plurality of chambers are made up of the first chamber to the fifth chamber, the heating temperature of the first chamber is 300 ℃, the heating temperature of the second chamber is 400 ℃, The heating temperature is 500 ° C., the heating temperature of the fourth chamber is sequentially increased to 600 ° C., and in the last fifth chamber, the heating temperature is raised to a heating temperature of 630 ° C. to braze the joined object.

The cooling unit cools the brazed base material while passing through the heating unit. The cooling unit radiates cold air to the base material through the water jacket.

The conveyor belt continuously transfers the base material from the supply stage to the discharge stage. The conveyor belt is caught by the driving pulley and the driven pulley, and the driving pulley is connected to the driving motor to drive the conveyor belt.

Accordingly, the conventional continuous brazing automation device is a preheating unit starting from the feed table while the workpiece to be joined with the filler metal is continuously transferred by the conveyor belt in the state set to the jig to join two or more base materials. Preheated while passing through, brazed while passing through the heating unit, cooled while passing through the cooling unit, and discharged to the outlet.

However, the conventional continuous brazing automation device configured as described above has the following problems.

First, in the case where the to-be-joined material supplied from the supply base is composed of the A base material and the B base material, the to-be-joined material is continuously transferred by the conveyor belt, and sequentially passes through the first chamber to the fifth chamber of the heating unit. When the thickness of base material A and base material B is the same or there is almost no brazing, wetting is good because the temperature difference does not occur between the two base materials. When the 10mm is made of a temperature difference between the two base materials caused a problem in that the poor bonding occurs as the wetting worse. That is, the wetting is the best at a constant temperature of the two base materials, A material continuously transported by the conveyor belt may reach 630 ℃ in the fifth chamber, but made of a relatively thick thickness than the A base material B base material does not reach 630 ℃, and therefore, the temperature difference between two base materials causes bad wetting. Therefore, the joining force of filler metal is incompletely acting between the two base materials, resulting in poor bonding such as cracks or pinholes at the joints. Will be.

Second, the to-be-conveyed material continuously conveyed by the conveyor belt is brazed by sequentially passing from the first chamber to the fifth chamber of the heating unit. A part of the joined object belongs to the fifth chamber but the other part is fourth. The temperature difference is caused to be partially different from the heating temperature of the object to be joined over the chamber, and thus there is a problem in that the weld state of the object to be joined is poor, resulting in poor bonding.

Third, the preheating unit intervenes the rapid thermal expansion of the object to be joined and the conveyor belt between the supply unit and the heating unit. In the process, the amount of gas used is reduced by using a gas curtain made of nitrogen gas so that atmospheric pressure does not act as a heating unit. There was a problem that caused the increase in cost.

An object of the present invention is to solve the problems as described above, by reducing the temperature deviation of the two or more base materials of different thicknesses to be brazed in a good wetting state of the filler metal can maximize the bonding force, The present invention provides a brazing automation device capable of maximizing bonding strength by blocking the inflow of air and brazing the joined object in an optimal wet state formed by a reducing component atmosphere by an atmosphere gas.
